Optional PFCCs
Power factor correction
capacitors (PFCCs) are designed
to provide power factor
correction for the compressor
motor. They are available as an
option.
Note: Remember that the PFCC
nameplate voltage rating must
be greater than or equal to the
compressor voltage rating
stamped on the unit nameplate.
See Table 15 to determine what
PFCC is appropriate for each
compressor voltage application.
CAUTION
Motor of safety overload
damage!
PFCC must be wired into the
starter correctly. Failure to do so
may cause misapplication of
these capacitors and result in a
loss of motor overload
protection and subsequently
cause motor damage.
